Our Tasks

Service Provider for the Internet Community

In our role as an impartial infrastructure service provider, we use our technical expertise and our powerful high-performance systems to ensure

  • The existence of a central register of all .de domains – for this purpose, we operate a registration database for central administration
  • Permanent availability of this register – anytime anywhere – for this purpose, we operate a global server network – the so-called name servers – for the ccTLD .de, as well as the German ENUM domain
  • That our members can register and administer domains for their customers – for this purpose, we provide an electronic real-time registration system for registration, deletion and updating of .de domains
  • That anyone can find out which .de domains are already registered - for this purpose, we offer our information service "whois".
  • That the Internet continues to evolve for the benefit of all – for this purpose, we host dedicated events and are actively involved in the present and future development of the Internet by participating in national and international bodies.
